	// TODO: Crowdin needs the strings to be quoted correctly and doesn't like incomplete quotes
	//       and Crowdin always outputs quoted strings if there are quotes in the strings.
	//       So, Gitea's `key="quoted" unquoted` content shouldn't be used on Crowdin directly,
	//       it should be converted to `key="\"quoted\" unquoted"` first.
	// TODO: We can not use UnescapeValueDoubleQuotes=true, because there are a lot of back-quotes in en-US.ini,
	//       then Crowdin will output:
	//       > key = "`x \" y`"
	//       Then Gitea will read a string with back-quotes, which is incorrect.
	// TODO: Crowdin might generate multi-line strings, quoted by double-quote, it's not supported by LocaleStore
	//       LocaleStore uses back-quote for multi-line strings, it's not supported by Crowdin.
	// TODO: Crowdin doesn't support back-quote as string quoter, it mainly uses double-quote
	//       so, the following line will be parsed as: value="`first", comment="second`" on Crowdin
	//       > a = `first; second`
